, invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in hydrants and fire-plugs; and the object is to produce a hydrant or fire-plug in which the entire operating parts are arranged at the bottom, and thereby the liability of freezing is prevented; also, to provide a means by which the waste water can readily escape and is got rid of; furthermore, to reduce the operating parts to a minimum, and thus simplify the construction; and, finally, to render the operation positive and reliable.

My invention consists in the construction of certain details and arrangement of parts, as will be more fully described hereinafter, and specifically pointed out in the claim, reference being had to the accompanying drawings and the letters of reference marked thereon.

Like letters of reference indicate similar parts in the different figures of the drawings, in which- Figure l represents a vertical cross-section of my improved hydrant or fire-plug. Fig. 2 is a cross-section on line of Fig. l. Fig. 3 is a cross-section on line y y of Fig. 1. Fig. 4 is a vertical section of the valve and operating-screw. Fig. 5 is a similar View of the same in detail.

In the drawings, A represents the main body or stock of the hydrant, made of any suitable size, and is provided at its upper end with the discharge-nozzle B and a stufiingbox, C, for the valve stern or rod D. This valve-stem is preferably made in sections, and is connected to the operating-screw E, which is seated and moves in the valve-box F. The valve-box is provided with the branch passage or side port, G, connected by the transverse ports g with the cylindrical part f of the valvebox at the upper and lower end.

About midway of the valve-box, and communicating with an annular recess, is a port, lz, through which any waste Water can escape, and out through the openings or holes e.

The valve consists of the piston H, attached tothe screw E by a swivel, h, and to the-lower end ofthe piston the disk-valve I is secured, and when the hydrant is closed said valve is seated on the seat t'. An elbow, K, is secured to the lower end of the valve-box, and conj tains a valve, L, which is guided in its place by a guide, Z, secured in the bottom of the elbow. 'Ihe valve L is forced open by a stem, h', on the piston H, and when released from pressure it is forced against its seat by the water-pressure from the water-main. This is a very important feature of my invention in connection with' the piston-valve and operating-screw.

The hydrants or fire-plugs can be made of any desired size, and may be made of any suitable material; and it will be readily understood by those skilled in the art that there is no liability of their gettingout of order. The parts are reduced to a minimum in number. The operating parts are all contained in the valve-box, which, by being placed entirely below the surface of the ground,- obviates any possibility of freezing, and thereby becoming inoperative or liable to be broken. There is no possibility of wastewater remaining in the cylinder part of the valve-box, as all will have to escape through the outlet-openings in the side of the valve-box; and, finally, the packing or wearing parts can be readily replaced whenever required.

The operation is as follows: When the valve I is raised from its seat by operating the screw in the valve-box by means of the valve-stem or operating-rod, the water will ow around the valve L, and passes through the ports g and branch passage G, and up through the hydrant-stock and its discharge-nozzle. When the hydrant is closed, any waste water that may have accumulated above the piston-valve H can freely escape through the side openings,

y e, in the valve-box. It is also Well adapted valve I, `and stem h', with the valve L in the to for a street-Washer or sill-cock. elbow K,a1l arranged substantially as and for -Having thus described my invention,what I the purpose specified, Y claim, and desire to secure by Letters Patent, In testimonywhereof I hereby affix my sig- 5 is 4 Y nature in presence of two Witnesses.
